Cumberland Steam Plant

Cumberland Steam Plant is a coal-fired power station owned and operated by the Tennessee Valley Authority near Cumberland City, Tennessee.

The Cumberland power station has two coal-fired generating units and "net dependable generating capacity" of approximately 2,530 megawatts. TVA states that "the plant consumes some 7,200 tons of coal a day." Construction of the Cumberland power station commenced in 1968 and was commissioned in 1973. According to the TVA the "plant consumes about 20,000 tons of coal a day."

Death and disease attributable to fine particle pollution from Cumberland Steam Plant
In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants. Fine particle pollution consists of a complex mixture of soot, heavy metals, sulfur dioxide, and nitrogen oxides. Among these particles, the most dangerous are those less than 2.5 microns in diameter, which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, and pneumonia each year are attributable to fine particle pollution from U.S. coal plant emissions. These deaths and illnesses are major examples of coal's external costs, i.e. uncompensated harms inflicted upon the public at large. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities. To monetize the health impact of fine particle pollution from each coal plant, Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.

Coal Ash Waste and Water Contamination
In August 2010 a study released by the Environmental Integrity Project, the Sierra Club and Earthjustice reported that Tennessee, along with 34 states, had significant groundwater contamination from coal ash that was not regulated by the Environmental Protection Agency (EPA). The report, in an attempt to pressure the EPA to regulate coal ash, noted that most states do not monitor drinking water contamination levels near waste disposal sites. The report mentioned Tennessee's Cumberland Steam Plant, Gallatin Fossil Plant and Johnsonville Fossil Plant as three sites that have groundwater contamination due to coal ash waste.

"High Hazard" Surface Impoundment
In July 2009, TVA reclassified the surface impoundment at Cumberland as having High Hazard Potential. The rating applies to sites at which a dam failure would most likely cause loss of human life, but does not assess of the likelihood of such an event. TVA had originally ranked all of its sites as "low" risk, but revised those rankings two weeks after the EPA released its list of 44 "high hazard" coal ash dumps.
